It is reported from the Prophet ﷺ with this same narration. Sufyan said that one of them said, "When you come to your bed in a state of purity," while the other said, "Perform ablution as you would for prayer." He then continued with the same meaning as the narration of Mutamir.
حدثنا محمد بن عبد الملك الغزال حدثنا محمد بن يوسف حدثنا سفيان عن الأعمش ومنصور عن سعد بن عبيدة
عن النبي ﷺ بهذا قال سفيان قال أحدهما إذا أتيت فراشك طاهرا وقال الآخر توضأ وضوءك للصلاة وساق معنى معتمر
